4a1b669ffe media: i2c: og01a1b: Add management of optional sensor supply lines 
Omnivision OG01A1B camera sensor is supplied by three power rails,
if supplies are present as device properties, include them into
sensor power up sequence.

bc0e8d91fe media: v4l: subdev: Switch to stream-aware state functions 
Switch all drivers accessing sub-device state to use the stream-aware
functions. We will soon remove the old ones.

Additionally drivers/media/i2c/s5k5baf.c and
drivers/media/platform/samsung/s3c-camif/camif-capture.c have been
manually changed as Coccinelle didn't. Further local variables have been
removed as they became unused as a result of the other changes.

Also Coccinelle introduced indentation by space in files
drivers/media/i2c/st-mipid02.c and
drivers/media/platform/rockchip/rkisp1/rkisp1-isp.c. This has been also
corrected.

b477adeb9a media: i2c: og01a1b: Drop system suspend and resume handlers 
Stopping streaming on a camera pipeline at system suspend time, and
restarting it at system resume time, requires coordinated action between
the bridge driver and the camera sensor driver. This is handled by the
bridge driver calling the sensor's .s_stream() handler at system suspend
and resume time. There is thus no need for the sensor to independently
implement system sleep PM operations. Drop them.

The streaming field of the driver's private structure is now unused,
drop it as well.

ed5c2f5fd1 i2c: Make remove callback return void 
The value returned by an i2c driver's remove function is mostly ignored.
(Only an error message is printed if the value is non-zero that the
error is ignored.)

So change the prototype of the remove function to return no value. This
way driver authors are not tempted to assume that passing an error to
the upper layer is a good idea. All drivers are adapted accordingly.
There is no intended change of behaviour, all callbacks were prepared to
return 0 before.
